Right now a user has to refresh a hosts inventory of Procs. They do this by
usually running the eventloop whenever they need a refresh or in a thread.
However on living systems the host really needs to refresh itself, to create
less of a burden on the user.
Marking as duplicate of bug #1788 - replace requestRefresh() with
Clients of the Host ask to be notified when something interesting happend and at
what frequency. The host then internally if/when to schedule refresh updates
and notify all interested observers.
